Time to break out the balls of yarn and catnip: it's the Friday open comment thread, where you get to pick the brains of your smartypants co-readers.

Post your tech questions, tell us your favorite holiday hacks, or just blow off steam with your Lifehacker compatriots in the comments below. (Speaking of feedback, we're spending the day poring over your comments and tweaking yesterday's redesign, so continue to let us know what you think in that thread.) For now discuss whatever's on your mind in the comments below, and we'll feature the best threads over the weekend. Get to yapping now! Photo by qu4ff.
